ANTI-FRICTION BEARING FOR CARS.

SPECIFICATION forming part of Letters Patent No. 475,007, dated May 17, 1892.

Application led January 14, 1892. Serial No. 418,012. (No model.)

T0 all whom it may concern,.-

Bo it known that I, CARL F. BUSCHNER, of New York city, New York, have invented an Improved Anti-Friction Bearing for Cars, of which the following is a specication.

This invention relates to an improved construction of an anti-friction bearing for cars of the kind in which the car-axle engages and revolves an anti-friction disk.

The invention consists in the various features of improvement more fully pointed out in the claims.

In the accompanying drawings, Figure lis an elevation of the bearing; Fig. 2,a Vertical longitudinal section thereof on the line x Fig. 4; Fig. 3, a vertical cross-section on line y fy, Fig. 1; Fig. 4, a vertical cross-section on line z a, Fig. l; Fig. 5, a horizontal sect-ion on line o o, Fig. l. Fig. 6 is a longitudinal section through one end ot' the caraxle; Fig. 7, a section on line q q, Fig. 6; Fig. 8, a top View ot' journal-box e; Fig. 9, an elevation of the invention, showing it applied to a four-wheel truck.

The letter a represents the car-platform slotted for the reception of the anti-friction disk or wheel b, which is placed between a pair of straps a of the platform, Fig. 5. To each of these straps thereare attached two upright guide-bars c c', which are vertically movable in the journal-boxes d of the antifriction disk b, such boxes being slotted for the reception of the bars. Below the straps a the front bars c engage in like manner the slotted journal-box e' of the car-wheel e.'

These front bars are extended below the carbottom, so as to be able to receive the box e', and they are connected at their lower ends to a suitable guard-rail c2. At the upper ends the bars c c are connected to suitable arched guards c3. The axle e2 of the car-wheel e is provided with a collar e3 in contact with and revolving the disk b. Belowthis collar there is a curved cross-arm f, that supports the platform a by spring-bolts f. To the crossarm f there are attached two front and two rear bars' g, carrying bolts g', to which the journal-boxes d of the anti-friction disks b are rigidly secured.

It will thus be observed that during the motion of the car it is free to jolt on the spring-bolts f', taking the guide-bars c c with it. These bars will thus play up and down in the journal-boxes d and e. The latter,

however, will always maintain their proper relative position, and though properly supported will not be eected by or participate in the jolting motion of the car. 1

Between the collar c3 and the curved arm f I interpose a curved dust-shield h. The collar e3 consists, essentially, of a steel tube e4, Fig. 6, having a downwardly-bent flange e5 in Afront and an upwardly-bent ange e6 at the rear. The collar incloses a rubber tube or packing 1T, surrounding the axle e2. The flange e is provided with elongated slots e7, through which pass screw-bolts es, by which the collar is attached to the wheele. Thus it will be seen that all the parts are properly connected and that still a yielding attachment is formedl between the car-Wheel and its axle. Thelrubber packing is entirely inclosed and all the parts turn together.

In Fig. 9 the invention is shown to be applied to a two-wheeled truck. Here the journalboxes d, in place of being attached to the bolts g', are attached to a continuous or common arm j, extending from one box to the other. This common arm is furthermore utilized to support the car-platform a by the spring-bolts f.

l. The combination of guide-bars c with a friction-disk h and car-wheel e., having boxes d e enga-ged by such bars, spring-bolts f', depending from the car-body, a cross-arm f, connected therewith, and upwardly-extending bars g, connected to the cross-arm and supporting the box d, substantially as specified.

2. The combination of a vertically-movable car-body with guide-bars c, projecting above and below the car-bottom, guards c3, that connect lthe upper ends of such bars, frictiondisk b and car-wheel c, having boxes d e engaged by the bars, and with spring-bolts f', depending from the car-body, and across-arm connected therewith and supporting the box d, substantially as specified.

3. The combination of friction-diskb with a collar e3, engaged thereby'and consisting ot` rubber packing t' and tube e4, having slotl ted [lange c6 and with Wheel e bolted to said flange, substantially as specified.
